1. INSTALLATION
1.2Transceiver Unit DS-620
Installation considerations
•Since the transceiver unit generates heat, install it in a dry,
•This unit is designed for bulkhead mounting to permit dissipation of heat. If bulkhead mounting is absolutely impossible, mount the unit on the floor leaving at least 350 mm clearance between it and the floor to permit dissipation of heat.
•Reinforce the mounting area, if necessary.
•Leave space around the unit for maintenance and checking. Refer to the drawing at the back of this manual for minimum recommended maintenance space.
•A magnetic compass will be affected if the transceiver unit is placed too close to it. Observe the compass safe distances to prevent disturbance to the magnetic compass (page i).
Use four hex. bolts (M10x20) to fix the transceiver unit to the mounting area. See the outline draw- ing at the back of this manual.
1.Screw in lower hex. bolts so there is 5 mm clearance between bottom of screw head and bulk- head.
2.Hang the unit on the bolts, then tighten the bolts.
3.Fasten the unit with upper hex. bolts.
